e4 is an incubator for community exploration of future technologies for the Eclipse Platform. The project has three principal aims:

Simplify the Eclipse programming model: This will reduce development and maintenance costs and enable a larger developer community to leverage the platform in their own Eclipse-based applications.

Enable the platform for use on emerging web-based runtime technologies: This will ensure the platform remains a compelling and viable application framework in a rapidly changing web technology landscape, and it will allow e4-based applications to leverage web technologies, while remaining insulated from specific technology choices that may quickly become obsolete.

Broaden participation in development of the platform: This reduces the risks associated with building on a platform largely funded from a single source. Having a large and diverse group of commercial backers, will ensure the platform remains vibrant and viable over the long term.
